\[ \boxed {x^{2} y^{\prime \prime }-4 x y^{\prime }+6 y=0} \] With initial conditions \begin {align*} [y^{\prime }\left (1\right ) = 3, y^{\prime }\left (2\right ) = 0] \end {align*}

Solution by Maple

Time used: 0.015 (sec). Leaf size: 15

dsolve([x^2*diff(y(x),x$2)-4*x*diff(y(x),x)+6*y(x)=0,D(y)(1) = 3, D(y)(2) = 0],y(x), singsol=all)
 

\[ y \left (x \right ) = -x^{3}+3 x^{2} \]

Solution by Mathematica

Time used: 0.017 (sec). Leaf size: 13

DSolve[{x^2*y''[x]-4*x*y'[x]+6*y[x]==0,{y'[1]==3,y'[2]==0}},y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to -\left ((x-3) x^2\right ) \]
